The Warhammer Alliance Forums have word that GamesWorkshop has filed a lawsuit against Curse, Inc. over the operation of this site dedicated to Warhammer Online (thanks MMORPG.com). Here's how they describe this puzzling turn of events:

We wanted to inform our community here on WarhammerAlliance.com that Games Workshop has filed lawsuit against Curse for operating and maintaining WarhammerAlliance.com. We feel this is a blatant disregard of the needs of Warhammer fans, and the community we've worked hard to set up. The lawsuit cites trademark infringement, cybersquatting (on the domain name), dilution and unfair competition. You can check out the full complaint here. It also states that GamesWorkshop was unable to contact anyone who was an administrator or decision makers at Curse (despite the numerous links on our site...).

We are shocked and surprised by this filing when this site, created in 2005, is well known for being one of the biggest Warhammer Online game fansite.

Having read TFA and the action, you can basically take your pick from:

- Evil Games Workshop! They want lawyer money, a valuable domain for free and to maximise the control it has over community discussions. This website is fair use, does not pretend to represent Games Workshop and builds up a community and hence is a good thing for the company. Or;

- Evil warhammeralliance.com! These guys are making money through advertising yet people only go there because it's about Games Worshop, therefore it is illegitimately profiting from another company's branding.

Personally I do not see how GW is losing anything from this "fan site", it's not like it's selling competing products, and I can't imagine anyone assuming it to be an official site. GW are widely known to be a litigious bunch of control freaks - am IRL friend of mine is well into it but he really dislikes the company. Apparently most fan sites had to come up with some agreement with GW to be allowed to operate (WTF?). On the other hand, given it's corporate ownership I'm not sure it's quite the "fan site" and yeah OK apparently they are making money.
